Cartography The regional forest mapping identifies automatically the different forest types by spectral analysis of satellite imagery/aerial and characterizes them based on the composition of forest essences, density and age. The level of map scale is determined by the type of imagery/aerial used and the level of preciseness as well as the expanse of the area to be drawn up. In addition to the classification of the forest plots, different map data references can be associated to the forest map. These data include among others the road network, water network, topography and / or other map information. Therefore, with these additional data and location-based knowledge of the forest heritage, the manager has a set of essential components for an efficient and integrated management of forest resources. b. Inventory The regional forest inventory provides an overall assessment of the amount of forest resources: - Number of wood - Tree density - Basal area - Average volume - etc. as well as an information on its geographical distribution. It is based on territorial poll for the calibration of the mapping. Data on the composition of forest massifs are integrated in the available database as queries in the Geographic information System (GIS). The quality of information produced by remote sensing is enabled directly in the field (ground truth).

Cartography Using high resolution satellite images (similar to aerial images) makes it now possible to carry out local forest inventories on the scale of the individual. In fact, satellite data have extremely advanced in recent years both in terms of spatial resolution (<1m) as in terms of spectral resolution (more channels in the visible, infrared, hyper spectral and radar ).In addition, their costs, availability and acquisition facilities make a high quality solution possible to ensure environmental monitoring and forestry in particular. Therefore, identifying, counting and localization of trees are processes that become affordable. b. Inventory The forest inventory provides an accurate assessment of the amount of forest resources (number of wood, tree density, basal area, total volume...). It is based on the counting of trees derived from the spectral interpretation of satellite images / aerial associated with accurate ground measurements for calibration. Data on the composition of standings are included in a database available for consultation as queries integrated in a Geographic Information System (GIS). This inventory can be completed by additional field surveys, targeted for specific needs that require more precision or characteristics that are not visible by remote sensing. By combining intelligent and efficient remote sensing and field measurements,. FOR offers the forest wealth managers rich and precise geo tagged information even on large areas. The services provided by.for aim to increase economic and environmental profitability of forest patrimony.

These services are described briefly below. We invite you to contact us for more information about our methodologies, their advantages and limitations. a. Management Plan The total geo-referenced inventory on the study area establishes specific qualifying and quantitative management plans to meet the most demanding criteria. It provides uniform information over large areas and allows the integration of multiple factors by crossing map layers and applications to achieve reliable statistical studies needed to establish management plans. b. Carbon stocks The estimation of carbon stocks is carried out based on the composition of forest standings and their geographical distribution. The total amount of carbon in the area of interest is assessed on the amount of carbon fixed per unit volume in each species or standing type. The accuracy of the estimate can be adjusted to the level of inventory carried out in advance and quantitative study of carbon fixation per unit produced. The purpose of. FOR is to provide location-based information to position favorably the manager for the preservation of carbon stocks. The interests are environmental (vital) and economic. c. Expertise The qualifying and quantitative forest inventory meets the demands of forestry expertise in large or small scale It can be configured to include different criteria of land or forest expertise. It provides location-based assessment which, crossed with the cadastral layers, defines exactly the value of heritage by cadastral parcel..for proposes an objective and quantifiable expertise, essentially for property insurance, for the available financial guarantee and within the context of inheritance tax. Thanks to the geo-location information of trees by species, one can estimate the operating profitability of certain species based on their accessibility and their exploitable potential volume. This service is based on the skidding distances, slopes, means of communication, accessibility, water network, operating costs and value on potential foot of each tree..for wishes, through this service,
FOR : the asset to manage your forest patrimony 6 to provide decision-makers and developers with relevant cross information that is necessary for the actual calculation of the profitability of a parcel on economic and socio-environmental base. d. Follow-up Multi-temporal inventory of forest patrimony ensures monitoring and control of the forest exploitations using geograpical information of exploitations. This evaluation will allow a continuous adaptation of forest management taking into account the latest events recorded and observed through the use of satellite imagery / aerial. As the forest changes, it is important to integrate the time dimension and the change detection in the management and the monitoring. Deforestation The inventory of forests analyzed periodically provides georeferenced statistics used to evaluate the extent of the problems of deforestation. The deforested or reforested areas are located and quantified with satellite imagery / aerial as evidence. This accurate inventory tool is homogeneous over very large areas and can standardize the method for monitoring deforestation and respond quickly to limit the consequences. As the satellite offer has become more and more rich and abundant, it is now possible to quickly cover a geographic area with a resolution of images suitable to monitor the evolution of natural resources. The assessment of potential cringe or growth of a forest area is therefore analyzed in relation to a reference time. The purpose of.for is to provide supervision and alerts addressed to illegal deforestation in order to preserve rights and protect natural areas that are under pressure.

The realization of successive inventories informs accurately the evolution of forest exploitations and wood stocks based on successive inventories. This service evaluates the difference between the quantities of exported wood (used in the timber industry) and the quantities of timber reaching the consumer, taking into account the transformation returns. This service checks that the delivered stock comes exclusively from the forest under concession. This service provides a sufficient or complementary global traceability to other techniques especially when the technical or budgetary means do not allow for traceability of each log. Control of certifications To meet the requirements of Forest Certification (PEFC and FSC), forest mapping tool provides a reliable inventory to check the correct application of certification criteria. Regular control can be applied to verify the status of forest exploitations, deforestation and reforestation and to locate in a quantifying way the volumes of certified wood. At the same time the tool is used to plot the volumes of certified timber and validate their certification throughout the timber industry. The purpose of. For is to simplify and make more effective control certifications through the provision of combined information from remote sensing and terrain. e. Prevention and management of natural hazards Health risks Services related to cartography inventory find all their senses in the prevention and the follow-up of health risks. Knowledge and location of the species permit to manage accurately and efficiently the health risks identified in the field. The availability of new satellites with wider spectral ranges, especially the infrared, increases the possibilities of monitoring the health of the vegetation. The research for declining trees or extent of a health problem are mappable. Fire and bush fires Remote sensing offers an unequalled vision for monitoring and detection of forest and bush fires. The information used permits to monitor large areas in near real time. The collected information feeds decision-makers and men of action in order to act efficiently and to protect the environment, property and of course the people. Storm damage (blowdown) Mapping of storm damage is an indispensable tool for a reliable and accurate estimation of the quantity of damaged forest. Based on a geo-located inventory, the delimitation of areas affected by the storm is done quickly from the acquisition of a new satellite image. Quantification and location of damage is a priority after a disaster. The cartography is also very useful to set priorities and guide the teams. f. WebGIS In addition to the services,. FOR proposes also the management of collected information in a dedicated computer system.

Research and development Always at the forefront of technical forest inventory by remote sensing, the team of experts investigates various issues of R& D. The results of this research are directly integrated in the chain of data processing in order to constantly improve the performance and quality of the results of forest inventory and mapping. a. Remote sensing for tropical forests - RADAR Cloud cover may be an obstacle to the acquisition of optical remote sensing data, especially in the humid tropical region. RADAR technology is an interesting alternative for the mapping of these forests. Thanks to recent technological advances, these images offer new opportunities for forest mapping in the tropics. b. Recognition of forest types - Hyper spectral The improvement of the recognition of forest species goes through the use of new spectral bands. Hyper spectral sensors record information in dozens of spectral bands, increasing the distinction of different forest types. c. Dendrometry - LiDAR The evaluation of the forest resources requires more reliable dendrometric estimations. The supply of the airborne laser (LiDAR) contributes to a detailed description of the forest in three dimensions. The analysis of this new information is crucial for forest inventory accuracy. d. Change detection Multi-sensors The forest monitoring by change detection techniques requires regular information. The multi-sensors approach allows juggling with the various information collected by earth observation satellites and thus assuring a multi-temporal follow-up independent of a specific type of satellite image.
